"-1 Application ined April 23, i910. yserial No. 557.122. l n I s' To all whom it may concern:

Be it. known that I, lnANii I. lloniaxcswonrii, a citizen ofthe United States, resid ing at Denver, in the county of Denver and State of Colorado, have iuvented'new and useful Improvements in Combined Gas and Electric-Light Fixtures, of which the following is a specification.

This invention relates to improvements inl combined gas and electric light fixtures and has for one of its objects the provision of a coupling for uniting the lainp soci-:et with the gas service pipe, the said coupling havking an opening to receive the conducting wires for the electric lamp and another opening separated from the tirst opening for establishing communication between the gas burner and gas service pipe.

Another object is the provision of an `electric lamp socket exterioi'ly provided with a shoulder having a stepped surface to form bearing surfaces for different diameters of casings employed to receive the gas service pipe and coupling, whereby the provision of the usual finishing collar which is frequently employed to couple one end of the easing with the lamp socket will be elin'iinated.

With these and other objects in view,

which` will more fully hereinafter appe:i i,'

the present. invention consists in certain novel details of construction ,and arrangement of iarts, hereinafter fully described, illnstrat in the accompanying drawings and more particularly pointed outy in the' appended claims; it being understood that various changes in the forni, proport ion, size, and minor details of the device. may be made, within the scope of the appended claims, without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings, forming a )art of the specitication;-l"igure l is a side elevation of a portion of a chandelier or hanger constructed in accordance with my invention. Fig. 2 is a longitudinal sectional view of the lateral arm of the cli. lier and lamp socket. Fig. 3 is a detail perspective of a lamp socket showing my improved head applied thereto. Fig. 4 is a detail perspective of t-lie coupling. Fig. 5 is a side elevation of the electric lamp socket. and one arm of a chandelier when the device fixture and showing a plurality of easings in longitudinalsection and 'applied to the head.

Similar numerals o f reference are einthroughout.

The hanger of the chandelier is designated by the numeral 5 and the lateral arm extending from the' lower end of the Yhanger by the numeral tn By reference to the drawf ings it will be seen that the. lateral arm 6A" -comprises an inner service pipe 7 surround# ed by ay easing S and arranged within the'ca's4 ing` and between the. latter and the Service I pipe 'i' are the coi'iducting wires l). i A

"lhc coupling forming one part of tliesub-y ject mattei' of the present invention is an ob` long cylii'idrical-shaped structure designated in general by the numeral 10; The c0iip.

ling is reduced in diameter froinone. end

to its middle portion, whereby a'sho'ul" der 1l is provided. By reference now to the drawings it. `will be seen that extending inwardly from the enlarged end of the casing is an anteriori)Y threaded opening 12 extending to the medial portion of the coupling and terminating in a lateral interiorly-threzuled opening 13 which opens through one side of the, casing, the. said opening 1.3 al ning with a similar opening formed in the casing 8, these openings receiving the threaded end of a gas cock 14, the opposite end of said cock heilig provided with a. burnerl5,whilethe outeiend of the opening l2 receives the end of the gas service pipe 7 'llie opposite or reduced end of the couplin 1t) is tapered and exteriorly screw-threadei as shown at lt, and formed in the said reduced end is an opening extending inwardly to a point ad'acent. to the lateral opening 13 whence. it terminates in an outwardly inclined extension 1i', which opens through that side of the coupling opposite to the opening 13 and on the rear side yof tlieshoulder 11. 'lhe conducting wires 9 are passed through the extension 17 and opening 16 and are connected with the socket in the usual manner. \\'ith this construction it will he manifest. that by virtue of the'eonstruction ol' the coupling the. conducting wires and interior of the gas pipe, will be out of .'onnnnnication.
